Title: Method and apparatus for bending or straightening sections and strips by means of rolls or rollers
Inventor: KEHNE LOTHAR
IPC: B27H1/00
Filed: 1988-05-05
Abstract: The method for bending sections and strips by means of rolls or rollers is carried out such that, during bending, the sections or strips pass between the rolls (rollers) and the instantaneous lines of contact between the rolls (rollers) and the section or strip to be bent are brought into agreement by desired value/actual value comparisons with the instantaneous lines of contact determined beforehand in relation to a reference plane. During straightening, the associated rolls (rollers) are deflected relative to the reference plane in phase opposition. For each of the individual roll pairs or rolls (roller pairs or rollers), the apparatus has a frame consisting of a top frame and a bottom frame, each top frame being mounted so as to be pivotable relative to the reference frame, and the frames being arranged so as to be displaceable perpendicularly to the reference plane and in parallel in or parallel to the reference plane.

Title: Sorting device
Inventor: ROBERT BOSCH GMBH STUTTGART
IPC: B07C5/344
Filed: 1988-08-12
Abstract: In assembly systems having automatic screwing, satisfactory screw material is necessary. Defective screws have hitherto mostly been eliminated by hand or by means of complex sorting devices. The novel sorting device is to separate out defective fastening components reliably and economically. The components or screws are transported in a suspended manner on an obliquely positioned rail (11). The balance of the screws (2) is disturbed by means of head repellers (16, 18, 19) and barrel repellers (20, 22), and the screws fall into a channel (6) for defective parts. Arranged downstream of the mechanical repellers is an electronic testing module (28) having eddy-current sensors (30, 31, 32) and a compressed-air nozzle (33) which blows defective screws down from the rail (11). The sorting device is suitable for feeding screws to screw spindles in automatic assembly systems. It can also be used, for example in the case of screw manufacturers, for providing a satisfactory screw material. <IMAGE>

Title: Device for the stationary braking of an electric power tool fitted with an angular gear
Inventor: GOECMEZ MUSA
IPC: B24B45/00
Filed: 1988-08-26
Abstract: In known angle grinders fitted with a safety brake system, the braking device consists of an electromechanical disc brake which is accommodated in the machine casing and considerably increases the overall length and weight of the angle grinder. In addition, there is here a relatively complex quick-clamping system for applying the clamping force to hold the grinding disc fast. The new device is intended to allow rapid braking of an angle grinder to a halt without increasing the overall length and without a significant increase in weight and, in a simple manner and without an auxiliary tool, to allow clamping of the grinding disc and relief of a clamping flange of the clamping pressure. In the new device, the output gearwheel (10) is mounted rotatably on the output shaft (13), which can be driven by the gearwheel (10) via a clutch arrangement and can be decoupled by means of an arbitrarily brakable control ring acting on the clutch arrangement as a result of the resulting relative motion between the gearwheel (10) and the output shaft (13) and can be subjected to the action of a blocking brake arrangement. <IMAGE>

Patent DE-3830002-A1 (DE)
Title: Device for a movable cuvette for comparative reflection spectroscopic measurements
Inventor: NAUMANN DIETER DIPL CHEM DR
IPC: G01N21/552
Filed: 1988-08-31
Abstract: For a cuvette arrangement for the discrete comparative analysis of liquid and film-forming materials, with the aim of raising the measurement accuracy and the scope of application of photometric methods, the object exists of developing a sample carrier which ensures an extremely uniform illumination depth for all the samples taken up as well as fully identical pick-up conditions, which is gas tight and easy to clean, so that it is also suitable for working with highly poisonous or highly infectious material. The object is achieved according to the invention, in that a suitably shaped carrying body which consists of reflective optically transparent material can be guided continuously through the bundle of measuring rays in such a way that individual regions of the prism surface are irradiated for comparative measurements. The cross section of the prism shaped as a carrier permits a single or multiple irradiation of the sample-carrying surfaces (Fig. 1). In a correspondingly shaped cuvette holder, the cuvette is moved on a slide. <IMAGE>

Patent DE-3837593-A1 (DE)
Title: Wavelength stabilisation
IPC: G01B9/02
Filed: 1988-11-05
Abstract: In interferometric metrology, the interference fringe spacing used as reference variable in the case of measurements in the free atmosphere is a function of the radiation frequency and of the refractive index of the air - which varies with the weather. The methods known so far for stabilising frequency do not prevent this dependence, but additionally render it necessary to measure the individual parameters of the air which influence the wavelength. A wavelength standard (5), the part of an interferometer (c, d, e, f) produced from a material which remains largely uninfluenced by the parameters which influence the refractive index of the air is used as a reference by means of which the frequency of the radiation source is regulated in such a way that the wavelength remains constant. The radiation thus regulated is at the same time a common source for a further interferometer for measuring state variables in the free atmosphere, e.g. distances, distances travelled or speeds. The wavelength stabilisation in conjunction with the laser diodes and integrated optical circuits permits the construction of small interferometers and their use in measuring instruments for which interferometric metrology has previously been unsuited. <IMAGE>

Title: Method for the control of fixed-length winding on a winding machine and length-measuring counter device for this purpose
Inventor: YAMAMOTO TAKERU
IPC: B65H63/08
Filed: 1988-11-14
Abstract: A length-measuring counter device for a winding machine for the winding of long-formate products, such as yarns, wires, sheet-metal strips or the like, is specified; by means of the device, the winding machine can be stopped accurately in accordance with a preset length-measuring value for the product; furthermore, a method for the control of fixed-length winding, in which the length-measuring counter device is used, is specified. The length-measuring counter device contains a correcting circuit which, according to an arithmetic value for a rate of increase in braking during a preceding stopping operation and a present working speed, precalculates a corrected inertia run-down length for the next stopping operation, with the result that the machine can be stopped accurately by taking into account a change in braking properties or in the working speed of the machine.

Title: Device for controlling an air-fuel ratio of an internal combustion engine
Inventor: HARADA RYOICHI
IPC: F02D41/00
Filed: 1988-12-14
Abstract: In a device for controlling an air-fuel ratio of an internal combustion engine an enrichment adjustment is performed when the engine is subjected to acceleration, the opening angle of a throttle valve being greater than a threshold value. A first sensor is provided for determining a first opening angle of the throttle valve and a second sensor for determining a second opening angle of the throttle valve. The enrichment adjustment is attained when the opening angle of the throttle valve is greater than the first value during a low engine speed condition and is attained when the opening angle of the throttle valve is greater than the second value during a high engine speed condition. The second sensor detects the depression of the accelerator pedal when the latter is depressed slightly beyond the fully opened condition of the throttle valve.
